METHOD OF AND MEANS FOR CLEANING AND REPAIRING CRANK-CASE 01L TUBES.

Application filed .Tune 6,

' an oil tube which has become clogged in use.

Another object of this invention 1s to provide improved means for repairing a crank case 011 tube which has been cleaned by the method herein described.

Another object of this invention is to provide an improved method of repairing an oil tube which has become damaged and clogged or susceptible of clogging in use.

Another object of this invention is to provide an .improved method and means for cleaning and repairing an oil-tube through the use of unskilled labor.

My invention consists in the method and means hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, it" which 1 Figure 1 is an elevation, partly in section, illustrating my improved device mounted in a'crank-case as required for practical use. Figures 2, 3 and 4 are detail views of the oil-tube and repair therefor.

In the constructionof the device as shown the numeral 10 designates the major portion of an oil-tube of common form employed in a well-known make of automobile and su ported in an inclined position in a crawl ca'se 11. ed in telescoping relation on the forward end portion of the tube 10 and is formed with a forward end portion 13, reduced in diameter, preferably by spinning, adapted to be received and supported in the front wall of the crank-case 11. A stop collaror clamp 14 is mounted adjustably on the tube '10 and is adapted toengage the rear end of the extension member 12 andlimit rearward movement thereof, thus retaining the re duced end portion 13 thereof in its seat in the fronttwall.

When an oil-tube is clogged or the forward end portion thereof becomes damaged and made susceptible of clogging, such as.

sometimes, occurs through blows thereon by a broken connectlng rod, it is customary to An extension member 12 is mount- 1921. Serial no. 475,529.

remove the timing plate from the front of the crank-case (having first removed-the radiator) and blow out the contents of the tube rearwardly by application of an airpipe to the front end of the tube, or, by lifting out and dismantlingthe crank-case to substitute anotherand perfect oil-tube; which operations are of varying but considerable magnitude and expense and require? skilled labor in the performance thereof.

My improved method of cleaning a clogged oil-tube or repairing one that is dented and damaged in the forward portion thereof, is as follows: First remove the bottom plate of the crank-case; then cut off the forward portion of the oil-tube to an extent of about six linear inches. through the use of a hack-saw inserted and operated through the opening in the bottom of the crank-case produced by removing the bottom plate; then removing the piece cut-off, being the forward end portion of the tube; then blowingout the contents of the remaining tube 10 rearwardly by applying an air-pipe to the cut forward end thereof; then applying the set collar loosely to the tube 10; then' telescoping an extension member 12 on the tube 10, introducing said member throughthe open bottom; then advancing the extension member 12 so that its end portion 13 seats in the hole in the front wall previously occupied by the forwardend of the piece of tube removed; then advancing the set collar 14 into abutting relation with the rear end ofv the extension member 12 and clamping it to the tube 10; and then replacing and securing the bottom plate on the crank-case.

This method does not comprehend the removal and replacement or substitution of the oil-tube, which consists in removing a bottom-plate from a crank-case, cutting off and removing the forward portion of an oil-tube in said crank-case, blowing out rearwardly the contents of the remaining portion of the oil-tube, applying a stop-device to the'last said portion of the oil-tube, applying a te escoping extension member to the front end of saidremaining portion of the oil-tube, ad-

justing the stop device into abutting relation with said extension member, and replacing said bottom plate.

2. The method of repairing an oil-tube which is damaged in its forward portion, which consists in removing a bottom-plate from a crank-case, cutting ofi and-removing the damaged portionof an oil-tube in said crank-case, applying a telescoping extension member to the frontend of the remaining portion of the oil-tube, and replacing said bottom plate.

3. T he'combination With an oil-tube from which a portion has been removed, of a stopcollar mounted adjustably thereon and anextension member adapted to be mounted telescopically on said tube and abutting said stop-collar.

4. T he combination With an Gil-tube," of an extension member having arednced end portion, said extension member being mounted telescopically on the forward end of said oil-tube, and means for limitingtelescopio movement of said extension member in one direction on said tube.
